View Full Version : Exhaust question

06-11-2010, 08:10 PM
Just picked up an exhaust today for my 2000 1.8t and was thinking about gutting the cat since ill already have my old exhaust off. Does anyone know what they're made of inside? and is it possible? A buddy of mine has a b6 a4 1.8t and when he went to gut his cat the inside was made of i beleive porcelain. and it wasnt possible to just shove something in there and gut it out. So before i go out and buy the new hardware and gasket for it i just wanted to see if anyone has done it or does everyone just use test pipes. thanks.
